A true accessory to the Smart Thermostat and The Netatmo Smart Radiator Valves - pack for district heating, the Additional Smart Radiator Valve allows you to control your home temperature even more accurately. Decide on the temperature of each room according to your needs! It's up to you to choose between two heating modes: Comfort Priority, which gives the Radiator Valve the authorization to heat certain parts to a temperature higher than that of the Thermostat; or the Priority Eco, which orders them on the contrary to limit the temperature. For even more savings, Smart Radiator Valves are equipped with Open Window Detection that automatically switch radiators off in rooms where windows are open. You can track and optimize your energy usage. Access your data history - indoor temperatures, heating schedule, boiler activity phases - and receive a personalized Energy Savings Report every month.
